Ok, sorry to bring this back up again. I asked before and kind of went to a working linux system. My question; On Win32, has anyone seen where you try to run the application but the window will not stay open. There are no errors, the window with 3D objects will not stay open. I was using a recent haskell 6.6.1 (ghc-6.6.1- i386-windows.exe). I asked before it seemed like the others suggested I use freeglut and use that. But I dont really need freeglut extensions. I am using basic opengl. I noticed that opengl is included in the ghc (mingw) I downloaded. Also, the code compiles, just doesnt run. The machine itself is a 3.2ghz, nvidia machine (win2k). I know opengl code should work. You can see the source here: http://octanemech.googlecode.com/svn/trunk/octanemech/src/misc/camera/ I compiled with: ghc --make MechCamera.hs -prof -auto-all -o $@ Basically the initialization aspect: import Graphics.Rendering.OpenGL import Graphics.UI.GLUT import Data.IORef mechLaunchGLWindow = do getArgsAndInitialize -- Initialize with the following settings -- Double buffer, RGBA color -- Alpha components supported, Depth buffer initialDisplayMode $= [ DoubleBuffered, RGBAMode, WithDepthBuffer, WithAlphaComponent ] initialWindowSize $= Size mechScreenWidth mechScreenHeight createWindow mechWindowTitle mechInitGL let mainCamera = initCamera (1.4, 4.2, -4.5) (0,0,0) (0,0,0) mainMech = initMech (0, 0, 0) (0, 0, 0) mainCameraRef <- newIORef(mainCamera) mainMechRef <- newIORef(mainMech) -- Set the OpenGL callbacks displayCallback $= displayGameLoop mainCameraRef mainMechRef -- Set the keyboard callback for handling actions keyboardMouseCallback $= Just (mechKeyPressed mainCameraRef) idleCallback $= Just idle mainLoop -- Berlin Brown [berlin dot brown at gmail dot com] http://botspiritcompany.com/botlist/?
